SPEGIFICAIIN forming part of Letters Patent No. 451,873, dated May 5, 1891.

Application filed December 18, 1390. Serial No. 375,073. (No modal.)

T0 aZZ wwm zTS nay concern: tail views illustrating features of my attach- Be it known that I, FRANK M. LA BOITEAUX, ments. a citizen of the United States, and a resident Referring to the parts, A is the base 01' of Cincinnati, in the county of Hamilton and stand, which may be of any approved form 5 State of Ohio, have invented certain new and or design. In the present instance it is a useful Improvements .in Fans, of which the tripod, preferably of cast-iron, fitted oenfollowing is a specification. trally with a socket support orbearing a, pref My invention relates to improvements in erably of brass. fans. B is a fan-motor of ordinary construction, 10 Its object is to impart a reciprocating roprovided witha downwardly-extending pivot tary motion to the motor or to the fan-shaft or spindle b to enter the socket-piece a in bearings, whereby the motor, when placed the stand A and support the motor, while peragainst the wall or in a corner of a room, mitting it to revolve or vibrate in a horizonwil1 deliver the force of the blast from the. tal plane around its vertical axis. The piece 15 fan-blades alternately to all parts et the room. a is bored from the top clownwardly With a The invention consists in pivotally mountcone-point drill, and the spindle Z) has its ing the motor upon its stand or support and lower end cone-shaped to fit the bore in the providing certain attachments, which will part a. cause the motor to vibrate upon its support. The motor-shaft 0 is provided at one end 20 I have shown in my pending application, with a fan D. Its opposite end projects Serial No. 354,213, filed J une 4, 1890, means throngh its bearing and is tapered to bearal for imparting a continuous rotary motion t0 ternately against the upper and under faces the motor carrying the fan-shaft bearings, of a segmental plate E, Which is supported whieh delivers the blast from the fan sucfrom the base A by a rod 6 and a curved 25 cessively to all parts of the room When the plate-spring 6', the lower end of which is semotor is located centrally in the room; but cured in a notch in theupper end of the rod as it is not always convenient to se locate it 6 by a set-screw,so that it may be adjusted to my present invention provides for an equal give the plate E proper inclination to receive distribution of the air to all parts of the room the point c alternately upon its upper and 50 when it is fonnd convenient to place the fan lower side, To the upper end of the spring against one of the side walls or in a corner 6 the segment E is centrally secured. The of the room. rod 6 is adj ustably securedin a socket-piece I Will first describe my invention and its ct, which is preferably cast as part of the mode et operation, referring; for clearness of base A. The segment E is horizontally in- 35 description to the acoompanying drawings, clined, as seen in Fig. 3, and has its ends in Which like parts are indicated by similar slightly curved in opposite directions, (oneup referenceletters wherever theyoccur throughand the other clown,) in order that the tapered out the various views, after which I Will parend 0 of the shaft 0 may pass under the segticularly refer to and point out in the claims ment when the motor is vibrated in one di- 40 the parts and combinations which I desire to rection and over it When vibrated in the opcover by Letters Patent as the law requires; posite direction upon its pivot I). The se; but as I am the first one to devise means for ment E is thus held in frictional contact with the accomplishment of the result attained by the shaft-point 0, which, when revolving at a my invention, I desire it to be nnderstood high speed, Will give such impetus to the mo- 5 that I do not limit myself to the speoific feator aronnd its axis b as to throw the motor V 1 turcs shown and described. around some distance after the point 0 has l Referring to the drawings, Figure 1 is a left the segment. To bring the motor back side elevation of an eleetric fammotor proand the shaft-point c again in contact with l vided with my improvements. Fig. 2 is a the segment, I employ the balance-swing F,

50 plan view of the base and attachments With the inner coil of which is secured to a collar the motor removed. Figs. 3, 4, and 5 are def, which passes over the spindle b, to whioh it is secured by a set-screw. The outer end of the spring is bent clownwardly at a right angle to enter a hole in the fixed stud a A setscrew is also employed to keep this end of the spring in place. Tire spring is so set that its nentral point is reached Wh en the shaft-point is at the centcr of the segment E, as seen in Fig. 2. This is accomplished by turning the motor to this position while the collar f is loose upon the spindle I) and then tightening the set-screw. XVhen the motor is vibrated in one direction by the shaft-point c revolving upon the upper side or face of the segment and in the opposite direction by its revolving against the under side, the spring Will stop it at the limit of its motion in either direction and retnrn it in the direction of its nentral point and again bring the point 0 in contact With the segment, thns acting as a spring-buffier t0 limit the oscillation of the motor and retnrn it in the direction of the central position.

'The point 0 may be made integral with the shaft or be made separate and fastened into the end of the shaft by screw-thread con nection, as seen in Fig. 4:. By the latter method my improvements may be attached to any of the fan-motors now in use.

It is obvious that the arc or segment E may be made to extend to nearly the limit of the path traveled by the point c and stops placed at each end, against which the pin 0 will strike after leaving the end of the segment and be retnrned by the stop against the opposite side of the segment. In this way the return-spring may be dispensed With; but this would cause jarring, which the spring overcomes.

WVhat I claim is- 1. In a fan-motor, the combination of the stand, the motor pivotally monnted thereon,

the motor-shaft, the fan secured npon one of the extended ends, and the fixcd segmental plate E, arranged to bear with its opposite faces alternately in frictional contact with the extcnded end of the shaft opposite the tan, and means to return said shaf.t in contact With the segment for the pnrpose of impart ing an oscillating motion to the motor, substantially as and for the pnrpose set forth.

2. The combination, with the fixed base, the fan-motor pivotally mounted thereon, the extcnded shaft-point c, the inclined segmental springplate E, arranged in the path of the said point to bear alternately up and clown against it to impart by its frictional contact with said point a circular oscillatory motion to the motor, and a return-spring t-o retnrn the said point alternately in contact with the upper and under sides of said segment, substantially as shown and described.

3. The combination, snbstantially as hercinbefore set forth, of the base, the motor pivotally mounted thereon,thebalance-spring having its opposite ends secured, respectively, to the pivoted motor and fixcd base, the shaitpoint c, and fixed segment E to impart by frictional contact au oscillatory movement to the motor when in motion.

4. The combination of the base A, having socket a, the motor B, having central pivot b to fit said socket, the spring F, coiled aronnd and secnred to said pivot and having its ontcr end fixed to the base, the motor-shaft C,'having the extended point c, the inclined segment E, rod 6, and spring 6 for supporting the same in the path of the shaftpoint, substantially as shown and described.
